EGG BEATER AND DRINK MIXER.

Application led March 26, 1924, SeriallNlo. 702,072. Renewed May 5,1926l My invention relates to egg beaters, drink mixers and similararticles for agitating liquids and aerating them, and has for its objectto produce an article of this kind that will quickly and thoroughlyagitate, aerate and mix any liquid or semiliquid substance that may betreated there- In the accompanying drawings:

Figure l is a side view of an article embodying my invention.

Fig. 2 is a central vertical sectionof the same.

. Fig. 3 is a perspective view of the cover and associated partsseparated from each other. Y

Referring to the drawings, 2 designates a vessel that serves as acontainer for the liquids to be treated. It is preferably formed ofglass'and is of elongated cylindrical shape. Its upper end is open; andnear such end the vessel is formed with an external flange 3,` abovewhich extends the cylindrical rim d which preferably tapers slightlytowards its upper edge. The glass or other material of which the vessel2 is formed is preferably slightly thickened on the inside asrepresented at 5 for a purpose which will be described.

6 represents the cover of the vessel 1t is formed of metal and comprisesa horizontal plate 7 at the edge of which is a folded rim 8 thatrisesiabove the plane of the plate 7 and forms a groove adapted to litthe rim 4c when the cover is applied. v The lower edge of the outer foldof the rim '8 is adapted to rest uponthe upper edge of the flange 3 whenthe cover is properly applied;

and the annular groove formed in the rim tapers upwardly and is of suchwidth that when the cover is applied there is a close, and practicallyair-tight, fit between the rim 4 and the folded flange ofthe cover.

The horizontal plate of the cover is perforated at 9 to form breathingopenings through which atmospheric air freely passes to and from theinterior of the vessel 2 during the operation of the article. y

10 designate a rod adapted to pass centrally through the cover 6 andcarrying dashers or agitating plates 11 at its lower end. These may beVof any preferred con struction. I prefer to provide two diskr shapedperforated metal plates spaced apart and of such diameter thattheiredges lie close to the interior wall of thevessel 2, to

serveas the dashers. The upper end of the rod l() is reduced andscrew-threaded as at 12 to receive a head 13 by which the rod ismanipulated. A coiled spring 14 encircles the upper endl of the rod, to`which it is united by causing itsupper convolution 15 to be clampedbetween the'head 18 and the shoulder at the lower end of the reducedportion 12 ofthe rod.

16 indicates an elongated hollow post that surrounds Vthe rod 10 belowtheV spring 1&1. To the upper end of this hollow post is secured a crossclamp 17 adapted to engage with the flange 3 of the vessel and hold thecover in place. VA collar 18, through which passes the dasher rod 10, issecured to the cross clamp 17 and serves as a bearing for the lowerconvolution of the spring 14. and also as a practicalv continuation ofthe post 16 above such clamp. The lower end of the hollow post isreduced in diameter and is externally screw-threaded as at 19, andpasses centrallyV through the plate 7 of the cover. A hollow nut 20engages-with the reduced screw-threaded end 19 of the post 16 and clampsthe horizontal plate of the cover between its upper end and the shoulderformed at the upper end of the screwthreaded part l19 of the post, thussecurely uniting the cover to the post, but permittino` ,its easyseparation therefrom, as indicated 1n Fig. 8, for cleansing or otherpurposes. The nut 2O serves as a gland or box to receive a packing 21that surrounds the dasher rod 10 and prevents any liquid from pass.- ingalong the rod and out through `the hollowV post l16.

22 indicates an umbrella disk secured to the post 16 just below theplate 7 of the cover. It is centrally perforated` to pass over thereduced portion 18 of the collar 16 and is held in place against theunderside of the cover by the nut 20. It is of such diameter that itsedge Vbears against the inner wall of the vess-el 2 where itisthickened, at 5, thus preventing the liquid which may reach the upperportion of thevessel during the agitating process from escaping. Thedisk 22 is perforated at 23 to form breathing openings, these being solocated as not to be in line with the breathing openings 9 in the cover.Any liquid that may pass through the openings 23 will be thus-arrestedby the plate 7 of the cover and will fall back upon the top of theumbrella plate 22 and will thence iiow back into vthe body of ythevessel 2 of the vessel either through the perforations substances, themixing of drinks, in fact the 23, or escape aroundthe peripheral edge ofthe plate.

The manner of operating thearticle de-- scribed will be apparent.Suiiice it to say that when it is to be used the cover, dasher Y andassociated parts are entirely removed,

and the liquid to be agitated is placed in the vessel 2. The cover isthen replaced and clamped in positioin, the dasher resting nearthebottoni ofthe vessel but not in contact therewith, being held at asuitable distance above such bottom byy the spring 14. The

operator now grasps the handle 13 and rapidly works the dasher rod upand down, the spring Y 111 preventing the dasher and lower end-of therod 10 trombeing carried into forcible engagement with the bottomr ofthe vessel which might be cracked'or broken should this take place. Thepassage of the dashers through the body of liquid causes it to be brokenup and violently agitated, thus eiiect-ing a thorough mixing `andaeration thereof, since there istree access ot air to the interior ofthe vessel, through the breathing openings 9 and-23. The liquid beingagitatedy will quickly become a frothy mass of much greatervolume thanthat occupied by the kmaterial when first placed within the vessel. Someot the material will Vthen inevitably reach the top of the vessel, butby the arrangements which I have de- -vised leakage thereotq isprevented. The engagement of the umbrella disk 22 with the thickenedwall of the vessel 2 very eectively prevents the escape of the materialaround VKthe edges of such disk. The packing 21 Within the nut 20prevents the escape of the liquid centrallyand along the reciprocating-dasher shaft or rod. The sealing of the cover by the tapering rim 4'entering and litting closely within the groove formed by the foldedrrini8 prevents, without the use ot' a gasket,theescape of any vliquid thatmay pass above the umbrella plate 22. The nonregistering perforationstormed respectively inthe horizontal-plate of the cover and the umbrelladisk insure free and ample supply of air to the interior of the body ofthe vessel, but do not permit the escape" of the liquid. If by chanceany small amount vof liquid should pass the openings 9 it would.

collect in the cup formed by the up-standing rim 8 at the periphery ofthe horizontal plate 7 of the cover.

I have found it very important that there should-be a i'ree passage ofexternal air to the interior of the vessel during the agitatingoperation to secure the desired aerating results, for wit-houtthese, aswould be the case should the cover hermetically seal the vessel 2, Ihave found it impossible to properly beat and aerate many substances.

My invention can be :put to many uses, i Vsuch as the beating of eggs,cream, and' other agitation, mixing and aeration of practically I haveshown the preferred form of my inventio'nVbutit will be understood thatthose skilled in the art inv practicing the same `are not to belimitedto tlie details herein shown, since these may be changed ascircumstances suggest, so long as the principle ofmy invention isfollowed, which invention is stated in the following claims.
